The book outlines various levels of practice: - Policies are the principles of practice to which the Unit conforms. These should be adhered to in all but exceptional circumstances. - Protocols represent the standard approach to practice in the Unit. These represent strategies that have been derived from evidence-based medicine, clinical experience and wherever appropriate, cost-effectiveness. Protocols are further designed into Guidelines, which are strategies to assist in clinical management. - Procedures are standard techniques performed in patients to facilitate the management protocol. However, these techniques may be modified depending on the limitations in the hospital. Eventually, the way a patient is managed will depend on the clinical situation.
